.RADIAN'I ELECTRIC HEATER Application filed August 29, 1928. Serial No. 302,688.

' My invention relates to a radiant electric heater, and more particularly to one havingseveral separate units adapted to be connected singly, in series and in parallel to produce 'difierent degrees of heat.

An object of my invention is to provide a heater having a plurality of windings, with an arrangement of heater units whereby an even radiation of heat will be produced throughout the heater, irres ective of the particular connections of t is individual units.

Another object of-my invention is to pro vide a new and novel support for electric heater units, whereby a p urality of units ma be carried on the same support.

ther objects and advantages will be pointed out hereinafter as the'description of my invention, taken in connection with the accompanying drawings, proceeds. v

In the drawings I have shown, by way of illustration, an embodiment of my invention where- Fi 1 is a front elevation of a heater unit 2 suita le for mounting within a recess in the wall of a'room.

Fig. 2 is a side elevation, in section, of the heater shown in Fig. 1.

Fig. 3 is a perspective View of a portion of so the supporting means for the heater units.

Fig. 4 is a modified form of a supporting I element.

In these drawings, 10 designates a housing member of sheet iron or the like which is adapted to be recessed into the wall of a room.

Within the body 10 there is arranged a pair of parallel vertically extending partitions 11 which are spaced from the side walls of the member 10, and arranged over the partitions 11 I provide a bafiie or cover 12 which acts to direct the radiated heat outwardly from the housing 10. This baffle 12 is flared out toward the back of the housing 10 at the point 14 and terminates out of contact therewith so that a restricted circulation of air will occur above the battle 12 and thus more efiectively prevent overheating at the tag of thehousmg 10. It :is also contempla to provide a suitable. ornamental illwork in across the front of the housing for the purpose of enhancing its appearance and also to prevent contact with the heater units.

.This grillwork forms no part of my invention and I have therefore, for the purpose of clearness, not shown the same in the draw- 5 mgs. l

At a point near the bottom of the housing 10, I show a suitable switch 15 which. is adapted to control the connections of the heater units and produce various circuits which will vary the flow of current and thus produce various degrees of heating, and extending horizontally above the switch 15 and between the partitions 11 I provide a pair of tie rods 16 upon which I thread a plurality of flat resistance unit supports 170 These supports 17 are s aced uniformly upon the rods 16 by means 0 insulating bushings 18, and are themselves made of a suitable insulating material. The resistance units are designated bythe numeral 19 and are shown as arranged in zig-za fashion over alternate supports 17 at the on s thereof. In Figure 2, I have shown an insulating connection strip 20 upon which suitable terminals are provided for the ends of the resistance heater units 19 and switch leads 21.

This connection strip 20 is preferably mount-- ed below the heater units so that no leads will be exposed to view from the exterior of the heater and the service leads 22 are inserted through a suitable opening in the side or back of the housing 10. 1

For a better understanding of the manner of supportin the individual heater units 19, attention is irected to Figure 3 of the drawings. In order to clearly illustrate, I have here shown an assembly wherein the bushing or spacers 18 are somewhat longer than those illustrated in Figure 1 and, as a result, the supports 17 arespaced further apart than is usual. Normall the supports 17 will be s aced substantial y as shown in Figure 1.

rom an inspection of this figure of the drawings, it will be' seen that the supports 17 are each provided with a notch 23 at the ends thereof and that thesenotches 23 are arranged in o posite edges of the supports so that when t esupports 17 are arranged alternat'ely in, reverse order, as shown, the

I arrangement of units.

notches 23 in the corresponding edges of the supports-17 will form a series of hooks or notches alternately at the top and bottom of the heater into which the resistance units may be suspended in zi -zag fashion along both edges of the assem led group of sup-' ports 17. As viewed in this figure of the drawings, one of the heater units 19 starts at the bottom and back of the left hand support 17 and then passes over the notch 23 at the top and back of the next support 17, and so on, and the other heater unit starts at the top and front of the left hand support 17 and passes through the notch 23 in the bottom and front of the next member 17 and so on to theend of the heater. By this arrangement, it will be seen that two distinct heater units may be mounted upon a single assembly of supports-17 and since the customary manner of constructing three heat heater units involves only two separate resistance units which may be connected singly, in series, or in parallel, it will be seen that by this arrangement with the supports 17 arranged edgewise to the front of the heater, I have provided, as each of the units is extended completely across the front of the heater, a

mounting for the two units which will pro-' duce a uniform radiation of heat from the face thereof. I

The modified form of the supports 17 shown in Figure 4 shows notches arranged in both edges at the ends with the notches located nearer the ends of the piece. With this type of support an assembly of same may be made Wltl'lOUl) first considering the manner of winding the heater units as they can be started at either end or side, whereas with the type of support shown in Figures 1, 2, and 3, some thought must be given to the manner of mounting and connection before the supports are assembled in order to get a desired final This support is further shown as provided with holes 2st spaced throughout its length. These holes 24 permit of additional circulation of air about the heater units and where the material is heavy or expensive, a reduction in weight or cost will also be effected.

From the above, it will be seen that I have produced in a radiant electric heater of the multiple heat type, a support for the heater units which will permit of a uniform arrangement of the heater units and result in a uniform radiation of heat across thefront of the heater, irrespective of the connections of the units, and while I haveshown for the. urpose of explaining my inventiona preerred embodiment thereof, I desire to have it understood thatI desire to cover by the appended claims all embodiments which fall within their spirit and scope.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. A resistance support for heater units comprising a pair of parallel extending rods, and a plurality of flat insulating members threaded in spaced relation'upon said rods having notches arranged in opposite sides at the ends thereof, whereby two distinct resistance elements may be supported thereupon in spaced parallel planes.

2. A resistance support for heater umts comprising a plurality of flat insulating members arranged parallel in spaced relation and having notches arranged in opposite sides at the ends thereof, whereby two distinct resistance elements ma be supported thereupon in spaced parallel planes out of electrical contact with each other, whereby more uniform distribution of the resistance units suitablefor a three heat connection may be obtained substantially as described.

3. A resistance unit for electric heaters comprising a plurality of spaced parallel extending members having notches formed in their edges at the ends thereof, and a pair of resistance units supported in parallel extending planes upon said members, said resistance units being laid along opposite edges of said members and engaging notches in each alternate member at the corresponding ends thereof.

4. A resistance unit for electric heaters comprising a plurality of flat insulating members arranged parallel in spaced relation, said members having notches arranged in opposite edges at the ends thereof, and a pair of resistance units adapted to be connected to produce different degrees of heating laced in zigzag fashion along the opposite edges of said supporting members and engaging the notches in alternate members as a means of support, whereby a uniform distribution of the heating elements will be produced irrespective of the connections thereof.

5. An electric heater comprising a housing having, spaced walls, a pair of horizontally gaging alternate insulating members atthecorresponding ends, whereby each of said units will be evenly distributed across the front of said heater.
